In 2020, the company "Stairs-A" developed a unique technology for the production of artificial marble from reactive powder concrete. We call it architectural marble-concrete (AMC).
Reactive powder concretes (RPCs) are concretes of the future that do not contain coarse-grained and lumpy fillers. The high fluidity of RPB allows you to use them for self-compacting high-strength concrete. Extremely high strength of RPB, reaching 120-160 MPa., Low water absorption (less than 1%), high frost resistance (more than 1000 cycles), high axial tensile strength (10-15 MPa) and bending strength (40-50 MPa) and high impact strength open up new opportunities for production of new high-strength finishing materials and in making a technical and economic breakthrough in concrete technology. For comparison, the average compressive strength of ordinary concrete M400 (B30) is 39.2 MPa, and this indicator is three times inferior to reactive powder concrete. That is why the company "Shodinka-A" chose RPB as a raw material for the production of AMB with subsequent cladding of concrete stairs . The engineers of "Stairs-A" considered all the nuances of using architectural marble-concrete as steps and landings of concrete stairs , namely: - all elements are covered with high-quality polyurethane varnish, which prevents the foot from slipping on the marble step. Polyurethane is used as a substitute for rubber, so your foot will never slip off the step. as it often happens on natural marble and granite stairs. At the same time, the process of grinding and polishing polyurethane varnish creates a high degree of gloss and makes our steps very similar to natural stone. - steps are reinforced with composite reinforcement for additional strength. - to avoid microcracks, we reinforce our artificial marble with polypropylene fiber. - on the back side of the steps there are honeycomb recesses for better adhesion of the glue with the step. Color variations of architectural marble-concrete are practically unlimited - we can choose any color range to order. White marble with gray veins, white-turquoise marble with yellow and dark green veins, white marble with golden-dark-gray veins - we will make everything that your imagination suggests!
